Question

• how to find radii of circle whose area is 154 cm square

Answer

• Radius = 7cm

Given

• Area = 154cm²

To Calculate

• Radius __?

Step by step explanation

Area Of circle = 154cm² ( Given)

We know that,

${\boxed{\red{\tt{Area \: Of \: Circle = πr²}}}}$

putting values,

Area = πr²

➫ 154 = 22/7×r²

➫ 154×7 / 22 = r²

➫ 1078 / 22 = r²

➫ 49 = r²

➫ r= 7cm

$\bf\underline{\underline{\red{HENCE:-}}}$

• Radius = 7cm
